Abstract: Provided are a method and a device for generating a virtual bearer in a wireless communication system. A mobility management entity (MME) acquires context information for a packet data network (PDN) connection generated through a Wi-Fi network, and generates a virtual bearer in a cellular network on the basis of the acquired context information. The virtual bearer may be generated by various methods according to whether a PDN connection mapped to the PDN connection generated through the Wi-Fi network exists in the cellular network and whether a default bearer exists in the cellular network.

Abstract: The present invention provides an apparatus and a method for performing timing synchronization in a wireless communication system. Particularly, the present invention is characterized in that resources for D2D communication and resources for performing cellular communication are identified, and resource information for the D2D communication is determined considering the number of D2D terminals and a cell size of a base station, has different frequency and time domains according to D2D terminals, and includes different time offset values. Accordingly, the present invention prevents, in advance, the generation of interference according to the D2D communication.

Abstract: A method of allocating resources according to the present invention comprises the steps of: allocating a signal having a first beam width from a first base station controlling a first cell to a predetermined resource; and allocating a signal, having a second beam width different from the first beam width, from a second base station controlling a second cell adjacent to the first cell to the resource. The signal having the first beam width may be a signal having a first priority, and the signal having the second beam width may be a signal having a second priority that is different from the first priority. Accordingly, a method for allocating resources is proposed which can stably receive signals even when a terminal that moves in a dense small cell structure is at a cell edge or a border region between cells.
